Working days and holidays

Hello Community, 

I have a question about wokring days. 

Before you send me links here, i read it and thats why i post this question. 

I read the page of Alberto Ferrari : http://sqlblog.com/blogs/alberto_ferrari/archive/2011/01/19/working-days-computation-in-powerpivot.aspx

After that, I create a calendar and an another table with all holidays here  :

I make realtion between my calendar and my holidays table, and its working. 

I begin with the Excel Working Days : and it doesnt works .

IF (OR ([@WeekDay] = 6, [@WeekDay] = 7), 0, IF (ISNA (VLOOKUP ([@Date], HolidaysTable[#Data], 2, FALSE)), 1, 0))

The first part is working : IF (OR ([@WeekDay] = 6, [@WeekDay] = 7), 0, 1) I have the good result. But how can i check in my jours fériés table if the date are present and if its the case then it's not a working days. 

Thank you in advance
